PUMP Russian patent published in 2011 - IPC F04F1/04 

FIELD: engines and pumps.

SUBSTANCE: proposed pump comprises fluid line and air line tightly jointed with rigid tank outlet, said tank accommodating elastic vessel communicated with condenser partially filled with low-boiling fluid. Frequency controller vessel is provided with cover to displace and be set to required rate fluid flow from outlet slot into capacity controller made up of a tank. Bottom of the latter is solid and furnished with branch pipe and valve, both incorporating programming means to adjust fluid flow rate into consumer vessel. Condenser partially filled with low-boiling fluid is arranged directly on capacity controller bottom to allow its cooling to complete rarefaction of elastic vessel space and to allow intermittent communication with cycle frequency controller located in well casing or pit. Cylinder with bottom incorporates suction valve and filter with limited fit support. Pump head incorporates inlet branch pipe tightly communicated with air pipeline and outlet branch pipe with check valve tightly communicated with fluid pipeline. Free end of the latter is communicated with cycle frequency controller tank.

EFFECT: higher efficiency.
